Intermolecular Interaction‐Facilitated Unimolecular Dehydration of Cyclohexanol on Rutile TiO 2 (110) Surface

ABSTRACT Alcohol dehydration reactions on oxide catalysts serve one of the foundational reactions in biomass valorization and fine chemical synthesis. The dehydration mechanism has been established as the unimolecular pathway (E1 and E1cb) or bimolecular cooperation pathway (E2)....

Topology-Dependent Free-Energy Barriers Underlying Activity Differences in Toluene Disproportionation over HZSM-5 and HMCM-22 Zeolites

Abstract Toluene disproportionation is an important industrial route to para-xylene, in which HZSM-5 (MFI topology) and HMCM-22 (MWW topology) are two representative zeolite catalysts that exhibit pronounced differences in their catalytic activity. To understand the molecular ori...

Capillary‐Driven Patterned Transfer of MoS 2 Arrays for Gate‐Tunable Optoelectronic Computing

ABSTRACT 2D materials have emerged as promising building blocks for next‐generation electronic and optoelectronic devices. The clean transfer of high‐quality, as‐grown 2D materials onto target substrates is a crucial step toward their integration into advanced device architecture...

Mechanistic Basis for 5-HT2AR Over 5-HT2BR Activation

Selective 5-HT2AR agonism without 5-HT2BR activation is critical for safe psychedelic-inspired therapeutics. Here, we systematically probe the ligand-binding pockets of 5-HT2AR and 5-HT2BR and identify steric and conformational constraints at the side-extended pocket (SEP) and ex...

Preliminary analysis for the joint autonomous orbit determination of the BDS-3 MEO satellites and lunar ELFO satellites based on inter-satellite links

Abstract A fundamental limitation of Autonomous Orbit Determination (AOD) for Global Navigation Satellite Systems (GNSS) constellations using Inter-Satellite Links (ISLs) is the inherent unobservability of the overall rotational bias, leading to continuous degradation of orbit de...

Nano-wrinkle waveguides for programmable polariton channeling

Abstract The intrinsic planarity of two-dimensional (2D) van der Waals (vdW) polaritonic media inherently limits the lateral confinement of vdW polaritons. Here, we transcend this geometric limit by introducing a deterministic strategy to engineer non-planar nano-wrinkle waveguid...

Cu-Catalyzed Cross-Coupling of (Hetero)Aryl Halides with Malonates: One-Pot Assembly of α-Arylacetic Acid Scaffolds

Abstract A direct synthesis of α-arylacetic acids from (hetero)aryl chlorides and bromides and malonates via Cu/oxalamide-catalyzed cross-coupling with tandem hydrolysis and decarboxylation is described. Enabled by tailored oxalamide ligand L4, the reaction proceeds smoothly unde...

Elucidating Ionic Programming Thermodynamics of Oxide‐Ion‐Based Electrochemical Random‐Access Memory Devices

ABSTRACT Electrochemical random‐access memory (ECRAM) enables analog conductance modulation by tuning the carrier concentration in the channel, making it a promising hardware platform for neuromorphic computing. Consequently, elucidating the quantitative relationship between the...

Dual‐Pathway Regulation by Diphenyl Guanidine Enhancing Sulfur Utilization in Sulfurized Polyacrylonitrile Synthesis

ABSTRACT The introduction of vulcanization accelerator (VA) can effectively reduce the amount of sulfur precursor in Sulfurized Polyacrylonitrile (SPAN) synthesis, improving sulfur utilization efficiency and thus promoting the commercial application of SPAN. Nevertheless, the mec...

Inner‐Sphere Nitrate Enables Highly Stable Aqueous NiO x Nanoparticle Inks and Promotes Phosphonic‐Acid SAM Anchoring for Efficient Inverted Perovskite Solar Cells

ABSTRACT Aqueous processing of NiO x nanoparticle (NP) hole‐selective layers suffers from a narrow precipitation window, poor colloidal stability, and poorly controlled surface chemistry that hampers the adsorption of phosphonic‐acid self‐assembled monolayers (SAMs). Here we intr...

Transcriptomic analyses identify TMPRSS4 as a shared biomarker in asthma and atopic dermatitis

Asthma and atopic dermatitis (AD) are common chronic inflammatory diseases that often co-occur, but the underlying shared biological mechanisms remain elusive. In this study, we performed WGCNA analyses on GSE6012 and GSE67472 datasets and identified 24 genes associated with both...

Dislocation Engineering Steers Reaction‐Induced Reconstruction of Vanadium Oxides for Selective Oxidation of Ethane

ABSTRACT Catalytic active sites or centers could evolve from their initial form under realistic reaction conditions due to the autonomous behaviors of the constituent atoms to adapt to the surrounding environment. Controlling such adaptability of metal‐oxide‐based catalysts is cr...

Evaluation of FatNav‐Based Prospective Motion Correction for Perivascular Space Imaging With T2‐Weighted MRI at 7 T

ABSTRACT Subject motion during MRI acquisition is one of the major factors limiting image quality and diagnostic value. Previous studies have demonstrated the effectiveness of prospective motion correction (PMC) in mitigating motion‐related artifacts. However, the effectiveness o...

Electrochemical Doping and Electronic Phase Transition of Thin-Film Perovskite LaNiO3 at Room Temperature

Abstract Rare-earth nickelates (RNiO3) offer great promise for applications in emergent electronic devices owing to their tunable electrical properties. LaNiO3 offers processing and operational advantages over heavier RNiO3 due to its easier synthesis and superior stability. Howe...

Robustness of Floquet Topological Time Crystals against Two-Level System Defects in Circuit QED

Discrete time crystals (DTCs) represent a nonequilibrium phase of matter characterized by spontaneousbreaking of discrete time-translational symmetry under periodic driving. While Floquet topological phases offer apromising route to stabilizing DTC behavior, their persistence in...

Chiral Nanostructured Cobalt Nanoparticles Confined in Zeolite for Syngas Conversion to Liquid Fuels at Low Temperature

DynamicBUS: restoring temporal dynamics from static ultrasound for improved breast cancer diagnosis

Abstract The clinical practice of archiving static 2D images from dynamic breast ultrasound (BUS) examinations leads to a critical loss of temporal information, vital for accurate lesion diagnosis. This data limitation constrains the performance of conventional computer-aided dia...

Genomic predisposition is associated with the direction of sex chromosome evolution

Sex chromosome evolution is among the most dynamic genomic innovations in vertebrates, yet why some lineages evolve XY while others evolve ZW remains unclear. Using chromosome-level genomes from 19 geckos, we found that gecko sex chromosomes originated independently from 16 ances...

Fiber Electronics: Integrating Logic, Photodetection, and Wireless Communication on a Single Optical Fiber

Abstract Optical fibers underpin the global information infrastructure, yet their role has remained largely passive—restricted to guiding light rather than processing it. Signal modulation, detection, and logic operations are still performed by external chips, imposing fundamenta...
